Abstract: 300,097. Lewandowski, A. May 19, 1928. Stereotype. - Stereotype plates which can be employed without the use of make-ready devices are cast from matrices prepared by sticking a sheet of paper or cardboard on the back of the flong, and, after the impression is made in the flong, grinding off the attached sheet at the parts corresponding to the darker tones of the print. A sheet of blotting-paper, attached to the flong by gum arabic, is preferably employed.

Abstract: 673,369. Locking levers & rods. HOBSON, Ltd., H. M., and WESTBURY, R. May 8, 1950 [June 2, 1949], No. 14838/49. Class 80 (iii). [Also in Group XXIX] A normally rigid member 23 used in a hy. draulic servomotor (see Group XXIX) collapses upon application of a predetermined axial load. A member 29 operating a control valve 36 of the servomotor is pivoted to a link 32 whose one end with the rim of the hole 55. The member 23 thus remains collapsed until the balls are reset by means of a conical plug 59. In a modification the housing is rotatable relatively to the tube 33 is pivoted to the collapsable member 23 and whose other end is linked to the valve. The member 23 comprises a tube 51 slidably mounted in a housing 22 and normally locked thereto by the engagement of a plurality of balls 53 with the rims of aligned holes 55, 56 in the tube and housing respectively. The balls are outwardly urged by a spring- pressed tapered plunger 52 slidable within the tube 51. Should the valve 36 seize in its housing, and the consequent axial load on the tube 51 exceed a predetermined amount, the balls 53 will be forced inwards against the action of the plunger and allow the tube 51 to move relatively to the housing 22. The member 23 is thus collapsed. On collapse, the centre Z of each ball 53 (Fig. 2) lies inwardly of the normal XY to the tapered head 57 of the plunger, X being the point of contact of the ball upon the application of a predetermined couple. Specifications 627,737, 673,370 and 673,371, [all in Group XXIX], are referred to.

Abstract: 650,499. Drum brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. June 4, 1948. Nos. 15061 and 17948. [Class 103 (i)] In a drum brake, particularly for aircraft, cooling is assisted by interposing an endless belt element between the drum and the friction element or brake shoes. The coefficients of friction of the drum, belt and friction elements are made such that when the brake is applied, the belt is carried around by the drum and is moved out of contact therewith so that it may be cooled by the slipstream. In Fig. 1, the belt 20 is shown interposed between the friction lining 10 and two externally contracting shoes 7 and 12, and is passed out of the brake assembly through a gate link 13 up the oleo strut, and round a guide member as shown in Fig. 6. The belt, which is preferably about 1 inch wide and 0.01 inch thick, may be made of a high thermal conductivity metal band, steel strips and copper gauze on cotton or asbestos fabric, endless metal wires in a side-by-side warp, or may comprise one or more belts of V-type. The belt has perforations with burrs which bite into a bonded asbestos covering on the drum. In Fig. 4, four smaller belts 24 are shown fitted side by side on the same drum, and spaced apart by metal dividing members 23. In Fig. 7 is shown a brake having both internal and external shoes, there being four belts 46, 47, 48 and 49 arranged so to encircle the individual shoes. Various other arrangements of the belts for both internal and external shoes are shown diagrammatically, including that in Fig. 15, in which the shoes 57 and 64 are radially applied and the belts are bands 58 and 65 of greater and less diameter than the drum 50.

Abstract: 1504517 Reducing interference PLESSEY CO Ltd 26 March 1975 [5 April 1974 27 Sept 1974] 15127/74 and 42143/74 Heading H4L In a circuit arrangement for separating out a desired signal from a channel containing both desired and undesired components, there is added to the signal originally in the channel to form a modified signal a signal from a further channel, containing at least the undesired component, the frequency and phase of the added signal being adjusted in dependence on the correlation between the modified signal and the added signal, to reduce the proportion of the undesired component from the modified signal. Band pass filtering arrangements ensure that the correlator works in (a) frequency band(s) wherein the wanted signal is absent the undesired component predominates. The undesired component may include a tracer signal passed by the filtering arrangements. Alternatively, a gating arrangement may ensure that the correlator means receives signals only when the unwanted signal predominates. As shown the modified signal is formed, at the output of coupler 22, at r.f., local oscillator 31 mixers 29, 30 and filters 32, 33 ensuring that the correlator functions at i.f., bandstop filters 24, 25 excluding the spectral range containing the output signal provided at 28 from the correlated signals. The arrangement may operate at r.f., in which case filters 24, 25 are tunable. Main and auxiliary aerials (1, 2), Fig. 1 (not shown) may receive the desired and undesired components, or the aerial (2) may receive only the undesired components, or the undesired signal may emanate from a co-sited transmitter and be conductively coupled to the auxiliary input. The arrangement may comprise a double superhet arrangement, Fig. 3 (not shown), the correlator operating at an i.f. to control the addition of the desired and interference signals at r.f., the separated, desired signal being fed at r.f. to a receiver (not shown). Separating out a plurality of desired signals, Figs. 4, 5 (not shown). Inputs equal in number to the number of independent, desired, signals may each receive a mixture of all the signals, and, by coupling into each channel phase and amplitude adjusted versions of the signals in the other channels, each phase and amplitude being adjusted in dependence on the correlation between band-pass filtered signals derived from the corresponding pair of channels, substantially pure desired signals may be derived. Alternatively, one channel may be separated out leaving an admixture of all remaining channels, the process being iterated with a stepwise decreasing number of channels until all channels are separated. The undesired components may comprise a broadband jamming signal.

The warning device is described applied to a combined filter and silencer of known type in which air is drawn in through a duct 1, Fig. 1, and passes through a filter element 3 to an outlet duct 6. The warning device 8, Fig. 1, which, as shown in Fig. 2 is provided with a whistle 17x, has a resonant cavity 9 provided with a compression spring 14 which urges the periphery of a diaphragm 16 into contact with a grommet 12. The whistle includes opposed conical plates 17a, 17b having holes 17c, 17d. When filter 3 is clogged .the pressure differential across diaphragm 16 produces oscillations of the diaphragm 16 and operation of the whistle 17x to provide the " chirping " note.
